STOPPING MECHANISM FOR INTERNAL-COJF IBUSTION ENGINES Application filed July 12, 1924.

To 07 "2 mm if mo concern l" e it known that l, tl'r'ro ltunnu, a citiizcn ot the United States, and resident; of Weslingr. in the county of (it-onto and State of ll'isconsin. have invented certain new and useful. ln'un'ovements in Stopping Mechanism tor Internal-Cmulmstion Engines: and I do herehy declare that the tollowin; i a full. clear. and exact description thereof.

This invention relates to stopping mechanism tor internal comhustio'n engines.

In a nuinher ol places internal comhustion engines are employed as for instance on the 'lari'n. in dairies. cheese 't'actorie-s and other places where they are required to perform a certain amount of work and. thereal'ter. are stopped at predeterminml times hy an attendant. This necessitates the presence of an a .tendant' to cut otl the fuel and the lulzricating' oil and needlessly increases the expense ot operation.

This invention is designed to overcome the above noted detects. and objects of such invention are to provide a stopping mechanism 't'or internal combustion engines which may he et at a 1n'edetermined time to hoth cut oil the fuel snpi ily and the luhricating oil.

Further ohject are to provide a stopping mechanism which may he readily installed upon existing; tvpes o't engines with a minimum oi change. which may he ch aply aml simplx produced. and which is free from omplicated and elahorate mechanism.

.tn emliodiment ot' the invention is shown in the accompanying drawings. in which:-

Figure l. is a rear view ot a standard form of internal combustion engine equipped with the stopping mechanism.

Figure 2 is a 'tracmentary side elevation ot the structure shown in Figure 1.

Figure 1-) is a 't'ragmentary plan view of the upper end ot the rod and oiler. such view hcino' partly in section.

The internal comhnstion engine comprises a cylitnler whose head is indicated at l and a hopper 3. This type of engine is usually provided with an oilcr 3 at its upper end which is controlled by means of a lever l: pivoted thereon. such lever being adapted to cut oil the oil when in the horizontal position shown in Figure it. and to allow tlow ot the lnlnicatinc oil when it is in a vertical posi tion. The engine is further equipped with astarting reservoir provided with a fuel control valve having a manipulating disk ti.

This fuel control valve is the normal operatino' valve for the engine.

ln applying' the stopping mechanism to the engine a shell '7 is provided preterahlv t'ormcd of sheetmetal and is equipped with dowmvardly extending lugs 8 which are holted to the engine in any eonvenient manner as hy means of the holts 9 in the engoie head 1 although it is to he understood that this device may he holted at any desi:cd point. The shalt rigidly carries a saddle it) within which an alarm clock 11 is seated and securetl. This alarm clock provided with the usual winding key it? for the time mechanism. The other winding: key for the Eltltlll mechanism is replaced hy means ol a disk or wheel 13 which screwed in place a suhstitute tor the winding key. This wheel is provided with a. pin l-l tor a purpose hereimittcr to appear.

The disk (3 for controlling the fuel is drilled and is equipped with a pin 15. These pins l-t and 15 are connected by means of a link it; so that motion from the wheel 13 may be transmitted to the control valve. hrarklt I? is adjustahly secured to a portion of the engine tor instance the, reservoir Ti. and carries one end of a tension spring: ltv. The other end of the tension spring" is secured to the lower end of the link us. as shown in Figure 2. The link 16 rigidly carries a diagonally upwardly extending}: arm l1) nhich terminates at; its upper end in a laterally projecting horizontal portion 2t). This horizontal. portion 520 is carried by means of a slotted guide 21 secured to the oiler 3. as shown in Figures 1 and in elongated loop 22 is formed of a portion of the horizontal extension and is adapted to manipulate the lever 4- ot the oiler. as will he descrihed later.

The operation of the ag'iparatns is as t'ollcws: The link it and the wheels or disks ti and 1.3 are turned in a clockwise direction. as in Figure 3. to open the fuel valve. This winds the alarm mechanism a little tighter. it heing um'lerstood that the alarm mechanism is kept in a wound condition. The pins 14 and 15 are then posi tioned on the right hand side of the cente s of the disks (l and 13. The arm 19 is moved upwardly and torwardly positioning the loop 2: directly over the lever 4. The lever 4 is then elevated and the engine is in running condition with a supply of fuel and oil A it.

furnished thereto. The alarm is set at the desired point and when the alarm is released by the clock 11, the Wheel or disk 13 rotates thus rotating the disk 6. Vhen, however, the pin 15 of the disk 6 is in its uppermost dead center position, the spring 18 operates to pull the pin 15 passed dead center, and thus permits the transmission 01 rotary motion from the wheel 13 to the wheel or disk 6 throughout a large portion of a revolution. The cut elf valve is thus closed at the desired time by rotation of the disk 6. In addition to this, the loop 22 moving downwardly and rearwardly rocks the lever 4 into its horizontal position, as shown in Figure 4 and thus cuts off the lubricating oil.

It will thus be seen that an automatic engine stopping mechanism has been provided, which may be most readily attached to standard types of internal combustion engines, and which will cut ofl both the fuel and the oil at a predetermined time Without requiring the attention of an operator.

It will further be seen that the device is simple, inexpensive, compact and readily applied to existing types of internal comlHlSillUll cu -Ines With 11 llllllllllllll'l l'llilll'fl 1-, :1 tllOI'QOf.

Although the invention has been described 3 in considerable detail, it is to be understood that the invention may be variously embodied and is, thereof, to be limited only as claimed.

I claim:

The combination of an internal combustion engine having a fuel control valve provided with a disk, an alarn'i clock secured to said engine and having a disk operated by the alarm mechanism, pins in said disks, a sul'rstantially vertical link connecting said pins, a spring secured to one end of said link and extending at right angles thereto adjacent said valve control, an arm extending laterally from said link and rigidly attached thereto and provided with a looped outer end, an oiler carried by said engine. and a control lever tor said oiler adapted to be positioned Within the looped end of said rod.

in testimony that I claim the foregoing I have hereunto set my hand at Mosling, in the county of Oconto and State of lVisconsin,
